TIME-SWITCH.

Application led August 19, 1915.

To all whom t may concern:

Be it known that I, HAROLD L. HAYNES, a citizen of the United States,residing at Chicago, in the county Of Cook and State of Illinois, haveinvented new and useful Improvements in Time-Switches, of which thefollowing is a full, clear, Concise, and exact description, referencebeing had to the accompanying drawing, forming a part of thisspecification.

My invention relates to time switches, and more specifically to timeswitches controlled by clock train mechanism.

Among the objects of my invention are to provide an improved release andbrake mechanism for time switches; to provide improved means whereby'theswitch may be actuated manually when desired, and to provide improvedmechanism for setting the switch;

Further objects will appear from the detailed description to follow andfrom the appended claims.

Fig. 2 i's a section on the line 2--2 of Fig. 1;

`Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig. 4 is a detail of the fan regulator and brake wheel;

Fig. 5 is a detail of the ratchet pawl mechanism for the switch;

Fig. 6 is a perspective view of one of the adjustable indicators; and

Fig.'7 isa somewhat diagrammatic view of the lower part of the switch,and two lighting circuits controlled thereby.

Referring now to the drawing in detail, I have shown my invention inconnection with a switch 10 which may be an' ordinary double pole fourpointl switch, or any type' suitable for controlling the circuit whichit is desired to control, power mechanism 11 for actuating the switch,release and stop mechanism 12- for controlling the power mechanism l1,clock mechanism 13 for controlling the release and stop mechanism 12,and lighting circuits 14 and 15 controlled by the switch 10. p

The switch 10 comprises the usual stationary and movable contacts whichare inclosed in a casing 16, a stem 17 connected Specification ofLetters Patent.

with the movable contacts for actuating them, a stem extension 18screwed onto the stem 17, and a switch button 19 screwed onto the stemextension 13. In the switch shown the cont-acts are arranged so that theswitch has three positions, in one of which positions both of thecircuits 14 and 15 are disconnected, in another of which only one ofthem is connected and in another of which both are connected. The poweror driving mechanism 11 comprises a spiral spring 2O one end of which issecured to a pin 21, a shaft A22 to which the other end of the spring issecured and which is rotatably mounted between the supporting plates 23and 24, a ratchet wheel 25 secured on the shaft 22, a pawl 26cooperating with the ratchet wheel 25, a spur gear 27 rotatably mountedon the shaft 22 and on which the pawl 26 is pivotally mounted, a pinion28 meshing with the gear 27, a shaft 29 on which the pinion 28 issecured rotatably mounted in the lplates 23 and 24, a gear 30 meshingwith the pinion 2S, a spring pressed pawl 31 pivotally mounted on thegear 30, and a ratchet wheel 32 secured on the stem extension 1S. Theshaft 22 is provided with a squared extension 33 for engagement with asuitable key for winding up the spring' 20. The release and stopmechanism 12 comprises a plurality of pins 34 secured on the gear 27, alug 35 movable into and out of the path of these pins 34, an arm 36 towhich the lug 35 is secured, an arm 37 pivoted at 38 to the supportingplate 23 to which arm the arm 36 is pivotally secured at 39, a brakeshoe 40 pivotally mounted On the arm 37 at 41, a brake wheel 42 withwhich the brake shoe 40 cooperates, a shaft 43 on which the brake wheel42 is secured rotatably mounted in the plates 23 and 24, a pinion 44secured on the shaft 43, a gear 45 meshing with the pinion 44, a shaft46 on which the gear 45 is secured rotatably mounted in the plates 23and 24, a pinion 47 secured on the shaft 46, and a gear 48 meshing withthe pinion 47 and secured on the shaft 29. A spring 49 vis provided, thetendency Ofwhich is to move the brake shoe 40 out of engagement with thebrake wheel 42. One end of this spring is fastened in a notch 50 in thearm 36 and the other end is secured to the plate 23 as shown at 51. Thearm 36 is bent outwardly, as shown at 52, to extend through an opening53 in the plate 23 and terminates in a cam portion 54 racing when it isreleased.

The clock mechanism 13 comprises indicating and switch controllingmechanism" 58 for controlling the release and stop mechanism 12, drivingmechanism 59 for the controlling mechanism 58, escapement mecha nism 60which may be of any ordinary type for regulating the movement of thedriving mechanism 59, and setting mechanism 61 for properly positioningthe dial. The controlling mechanism 58 comprises a dial 62 which isrotatably mounted on the hub 63 of a gear 64, a plurality of combinedcam and indicator members 65, the position of which with respect to thedial determines the time of operation of the switch, and a pointer 66for coperation with the figures on the face of the dial to aid insetting the dial. The dial 62 is adjustably held in position on the hub63 by means of a spring washer 67 and a nut 68 which engages a threadedportion 69 of the hub 63. The pointer 66 is pivoted at 70 to the plate23 and is adjustably held in position by means of a screw 71 whichextends through a slot 72 into the plate 23. `This pointer 66 is madeadjustable so that in case the switchy does not operate precisely at thetime indicated the pointer can be adjusted to make the necessarycorrection.

The driving mechanism 59 comprises the gear 64, a gear member 73 havinga gear portion 74 meshing with the gear 64, and a gear portion 75, astud 76 secured in the plate 77, a pinion 78 meshing with the gearportion 75, a shaft 79 rotatably mounted in the plates 77 and 79L towhich the pinion 78 is secured, a gear 80 having a frictional drivingconnection with the shaft 7 9, a pinion 81 secured to the hub of thegear 80, a gear 82 meshing with the pinion 81, shaft 83 on which thegear 82 is secured, a pinion 84 secured on the shaft 83, and a springactuated gear 85 meshing with the pinion 84. The shaft on which the gear85 is secured is provided with a squared end 85a for engagement with asuitable key for winding up the spring.

The members 65 each comprise an annular portion 86 surrounding the hubportion 63, a portion 87 which is bent over the edge of the dial 62 toform a pointer for cooperation with the figures on the face of the dial,and a lug 88 for engagement with the cam portion 54 'of the arm 36.

The setting mechanism 61 comprises a thumb wheel 89 secured on the endof the shaft 79, the pinion 78 previously referred to, also secured onthe shaft 79, and the gear member 73 and gear 74 previously referred to.The dial 62 is provided with figures corresponding to the hours of theday and night, as indicated at 90; the hub of the gear 80 has africtional driving engagement. with the shaft 79 as indicated at 91whereby the dial 62 will ordinarily be driven from the pinion 81 throughthis frictional engagement by means of the shaft 7 9, pinion 78, gearmember 73 and gear 74, but which frictional engagement will also permitthe shaft 79 to be rotated within the hub of the gear 80 by means of thethumb wheel 89 to permit the setting of the dial 62. Spacing members 92are provided to hold the plates 77 and 7 9a in their proper relativepositions. The plates 77 and 79a are held together and to the plate 23by means of screws 93. Clips 94 are provided for securing the mechanismwithin the casing 95.

Theuse and operation of my improved mechanism is as follows. The twocircuits 14 and 15 may be the circuits for illuminating two differentdisplay windows, and it may be desired that the lights in one of thesewindows should be turned off before the lights in the other. Assumingthat it is desired that the lights in both windows should be turned onat a certain time, as six ocloclr, and that it is desired that thelights in one window be turned ofi' at ten oclocl; and in the other ateleven oclock, the members 65 are adjusted so that their pointers willindicate, respectively, six, ten and eleven in the evening, and the dial62 is adjusted so that the pointer 66 indicates the correct time of dayon the dial. The dial 62 is driven by the clock train until the lug 88of the pointer 65 which is set at six ocloclr engages the cam portion 54of the arm 36 to force it to the left, as shown in Fig. 3. This willmove the lug 35 from in front of one of the pins 34 and permit thespring 49 to draw the arm 36 down to move the brake shoe 40 out ofengagement with the brake wheel 42 to permit the driving mechanism 11 tooperate the switch 10 to move it to a position in which both of thecircuits 14 and 15 are connected to cause both windows to beilluminated. The movement of the switch will continue until one of thepins 34 on the gear 2-7 comes into Contact with the lug 35 which hasbeen' drawn over into the path of this pin by means of the spring 49.The movement of the pin 34 will raise the arm 36 to cause the brake shoe40 to again engage the brake wheel 42 to bring the driving mechanism 11to a stop. The spacing of the pins 34 and the gear ratio of the drivingmechanism 11 are such that the switch 10 will be moved from one positionto the succeeding position at each releasing movement of the arm 36.When the lug 88 on the pointer which is set at ten oclock engages thecam portion 54 it will cause the operation previously described to berepeated to move the switch 10 from a position in which both of thecircuits 14 and 15 are connected to illuminate both windows to aposition in which one-of the circuits will be disconnected. When the lug88 on the pointer which is set at eleven oclock releases the arm 36 itwill cause the lights in both windows to be turned off.

If it is desired to operate the switch 10 manually independently of thetime controlling mechanism, which might be the case if it got darkearly, the switch can be operated by means of the switch button 19. Thisoperation by means of the switch button 19 will simply cause the toothof the ratchet 32 which is engaged by the pawl 31 to move away from thepawl 31, but not, however, sufficiently far to allow the pawl 31 to dropin behind the succeeding tooth on the ratchet 32, (see Fig. After theswitch has been thus manually Operated the releasing movement of the arm36 which takes place later will not cause the switch 10 to operate yasthe pawl 31 will simply ride along the ratchet wheel 82 until it catchesup with the tooth which has been moved a way from it. It will cause aslight movement of the ratchet wheel, but not suflicient to cause theoperation of the switch.
